How to Use Anti Hydro Products for Climbing

I can pretty much tell the humidity of your skin when I shake your hand. It's kind of like cooking how like you cook a piece of meat and you can like touch it and tell how how done it is. But then of course people are always like super self conscious or or like what's it called skeptical. Of like actually having something to solve the problem, but they know it's a problem. While you're wiping your own hand on your shirt. And the same thing in their skin is super dry. Like you shake people's hands that their skin super dry and it's like shaking a crocodile's hand.
